Counter Flashing
Counter flashing is an important roofing technique that helps prevent water from getting behind or under the main roof materials where they meet walls, chimneys, or other vertical surfaces. Think of it as a second layer of protection that works together with the main flashing. While regular flashing is installed first against the roof, counter flashing is the piece that goes over it and into or against the wall. This two-part system creates a more reliable water barrier. When reviewing resumes, you might also see this term written as "counterflashing" (one word) or "counter-flashing" (hyphenated) - they all mean the same thing.
